r IMPROVEMENT IN1@1mm-BINS.

f LFITCH RAYMOND, of- Oleveiand, in the-county of Ghuyahoga and State of Ohio, have vinvented certain v new land useful Imprvements in Grain-Enns-` -'lheinature `of my invention relates to a certain arrangement of .bins for storing wheat, corn, &c./, where- `by the grain is protected from dampuess,lrust, molding, `and heating, by.` subjecting the same to an ini-j ;pelled current or currents of heated or cold air, when `in `said bin, as l hereinafter "set forth and described, and whereby Vthe grain in the bin may' be fumigated or perfumed by impreguatiiig or charging the air vso forced in'with anydisinfectaut' or perfum-eor .vapore ized substance, as desired.

inthe-accompanying drawing#- i l Figure 1 representsa plan view of a-grain-bin;

Figure 2 is a ,Vertical `central sectional View, `illus- Figure 3, a like 4View, illustrating another form of thesame l The drawing merely illustratesthe invention, which,

for the sake of convenience, is sustained in an *upright `positionybetwe'eu'and .upon two legs,a ud

mightlas well be in any'foru1desired,^as in the one shown I make `noclaim upontlie general form ofA the vessel. g L

Brepresents the platform. AA, the legs.`

and E' E the pipes or conduits through which is tobe conductedfintov the bins. fire the caps, strainers, or air-chamber, through he air is to be admitted into thelgrain, and by` )whiclif'the grain is to be held within the bin.

O Cfare the wire-cloth or strainers,which are fast- "fened over theopenings on the inner ,side of the bin,

land answer the same purpose as the above-described dd are air-chambers cut 'in the walls and d D ist-he `exit for the grain atv the bottom', to be opened and closed inV any ofthe usual modes.'

The" form of lventilators. shown at O C seem best adapted to use where the walls ofthe bins are not vertical, butjslopiug, as shown in the drawing, as the f ainforced in through the pipes E E would enter through the perforations e e `in the topand t-hose in the side c cat the same,t ime,' a nd they'ma'y be made of strong wire-cloth or perforated metal, or other malterial suitable for the purpose, and. properly fastened to the walls of the ;bin, and sustained in proper form and pp sitiou by suitable frames of wood ormetal fastcned also to the walls. i Perforated metal plates/are deemed better for this Vform of device, Vas; they are stronger, .and less liable to f be stopped up by the grainthan` the' other form here-y l inafter described.

form of the orifice,`.whilethe jaggedpoiuts made by `the operation of punching ou the inner side would tend to 4prevent thegrain from choking foratious.

vThe perforations should be as large as maybe, with'- up the per- Aout heilig large enough for the passage of the grain.

` The-form shown in C' C', in iig.` 3, may be used upon the bottom and upon the walls, whether inclined 0 1' perpendicular.

The pipes E' E may be fixed in holes bored from the outside through a ,part of tlletheknessv of the walls, and 'larger recesses should be cut for air-cham bers dd on the inner side,an d the strainer of wirecloth or other suitable material, ff, fastened over the recesses on the inner sides of the .walls,'and flush therewith. f

There 'may be any desired number of either or .both

forms of these deviceson either the sides or bottoms ofthe vessels..A

' The number, size, and location, should depend, of

course, upon the form and size of the vessel; but, if

deemed expedient, the pipe E and air-chamber d, in

the form shown at O2, iig. 3, may be cast in one piece of metal, space being made in the timber of the wall' for the chamber,` and a hole bored for the pipe E, or the piece so cast may be located as sli'o'wn at C1, iig. 3, the air-chamber being wholly within the vessel, andV the pipe extending through from the inner surface of the Ywall through it.'

. Iii-either case'the perforated metal, wire-cloth, or otherlike' material, should. be fastened over `the top of the chamber, to closev it against grain, but admit the air from it into the bin.

By means' of these devices, and with the aid of any good blowing apparatus, pure air may be forced into every portion ot' the mass of grain, and, be made to carry off the surplus heat, moisture, aud the infectious vapors of decay. l

` Vihat I claim as new, and desire to secure by Let l Witnesses:
